Description: Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.-Wavelets have been widely used in many sign al and image processing applications.

Description: 运动估计是视频压缩中帧间预测编码的关键技术之一，在各个压缩标准中都广泛使用了基于块的运动估计技术。由于运动估计通常具有较大的运算量，因此对压缩性能具有重要的影响。本文在分析了视频序列的特点和对现有的快速搜索算法深入理解的基础上提出了一种改进的快速运动估计搜索算法，通过实验表明该算法对压缩性能有了较好的改进。
-Video Compression interframe predictive coding one of the key technologies. in various compression standards has made extensive use of block-based motion estimation technology. As the motion estimation is usually larger amount of computation, so the compression performance has a significant influence. Based on the analysis of the video sequence and the characteristics of the existing Quick Search Algorithm in-depth understanding on the basis of a modified Quick search motion estimation algorithm, experiments show that the algorithm has better compression performance improvements.

As modern society to the requirements of the communications business continued to grow, image communication and communication network capacity contradictions are becoming more prominent. Especially with the huge amount of data digital image information more difficult for transmission and storage, has greatly restricted the development of image communication, image communication has become a bottleneck in development. Image compression technology for the application by fax, video-on-demand, video-conferencing, transmission of medical images and other areas has brought huge economic benefits.
